ABRAHAM HORROCKS, OF BARDOLPH, ILLINOIS.

BRlCK AND 'TlLE MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,8 71, dated March 25, 1884:.

Application filed April 23, 1883. (N model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM HORROOKS, of Bardolph, in the county of McDonough and State of Illinois, have invented new and useful Improvements in Brick and Tile Machines, and I do hereby declare that the following is a full, clear, and exact description of A the same, reference being had to the accompanying drawing,which forms part of this specification.

This invention relates to that class of brick and tile'machines where the clay is tempered and forced out through the dies by means of angers; and its novelty consists, first, in a vertical chamber, in which is placed a vertical pugging or mixing and forcing screw, said vertical chamber joining a horizontal chamber, in which is placed ahorizontal mixing and forcing screw,which extends entirely,

across the lower end of the vertical chamber, and is enlarged at the inner end under the vertical pugging-screw, so as to fill the space between the bottom of the horizontal chamber and the lower end of the vertical pugging-screw, whereby the clay, while passing through the machine, is thoroughly mixed and forced through the dies. without liability of packing or clogging in the machine.

My invention consists, further, in facing the blades or flanges of the pugging or mixing screw with steel plates, which enables them to withstand a greater amount of wear with a less amount of friction, as will be hereinafter more fully set forth.

In the drawing, which represents a vertical sectional view, A is a vertical chamber,which tapering, the enlarged end being placed under the lower end of the vertical puggingscrew, so as to fill the contour of the horizontal chamber, the blades of the screw being madeasufficient size to fill the space between the bottom of the horizontal chamber and the lower end of the vertical screw in the vertical chamber. This is an important feature of my invention, as the clay, which is fed in at the upper end of the vertical chamber, is kept in a continuous motion injits passage through the machine, is thoroughly and inter.- mediatcly mixed in all its parts, and all packing or clogging of the clay in the chambers, both vertical and horizontal, is entirely obviated.

c are the screw bladesor flanges.

s .9 represent steel plates, which are bolted or riveted to the screw-blades c on the working or the side which receives the pressure. These steel plates cause the screw to wear much longer, and by use receive 'a high polish, which greatly reduces the friction of the screw while pressing the clay through the machine, the advantages of whichare obvious.

The operation is as follows: Motion is imparted to both screw-shafts in any convenient manner, and the clay is fed in at the top of the vertical chamber A, and by means of the blades of the screw the clayis forced down onto the horizontal screw 13, which forces the clay forward and out through suitable dies secured to the outer end of the horizontal chamber. (Dies not shown.) By this combi nation and arrangement the clay is kept in a constant motion, from the time it enters the machine until it is forced out in the proper shape for brick or tile.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
